Title
(EN) POLYPEPTIDES FOR DETECTION AND TREATMENT OF CORONAVIRUS INFECTION
(FR) POLYPEPTIDES DE DÉTECTION ET DE TRAITEMENT D'INFECTION À CORONAVIRUS
Abstract
(EN) To address the need in the art, the inventors have comprehensively characterized the SARS-CoV-2-specific B cell repertoire in convalescent COVID-19 patients and generated mAbs against the spike, ORF8, and NP proteins. Together, the inventors' data reveal key insight into antigen specificity and B cell subset distribution upon SARS-CoV-2 infection in the context of age, sex, and disease severity. Aspects of the disclosure relate to novel antibody and antigen binding fragments. Further aspects relate to polypeptides comprising the antigen binding fragment(s) of the disclosure, and compositions comprising the polypeptides, antibodies, and/or antigen binding fragments of the disclosure. Also described are nucleic acids encoding an antibody or antigen binding fragment of the disclosure.
(FR) Pour répondre au besoin de l'état de la technique, les inventeurs ont complètement caractérisé le répertoire des lymphocytes B spécifiques au SARS-CoV-2 chez des patients atteints de la COVID-19 convalescents et des mAb générés contre les protéines de spicule, ORF8, et NP. Conjointement, les données des inventeurs ont révélé un aperçu clé en une distribution de sous-ensemble de spécificité antigénique et de lymphocytes B lors d'une infection à SARS-CoV-2 dans le contexte d'âge, de sexe et de gravité de maladie. Selon certains aspects, la divulgation concerne un nouvel anticorps et des fragments de liaison à l'antigène. D'autres aspects concernent des polypeptides comprenant le ou les fragments de liaison à l'antigène selon la divulgation, et des compositions comprenant les polypeptides, les anticorps et/ou les fragments de liaison à l'antigène selon la divulgation. La divulgation concerne également des acides nucléiques codant pour un anticorps ou un fragment de liaison à l'antigène selon la divulgation.
